The 212 decoders are a series of CMOS LSIs for remote control system applications. They are paired with Holteks 212 series of encoders (refer to the encoder/decoder cross reference table). For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen. Features/Specs: Received codes are checked 3 times Address/Data number combination HT12D: 8 address bits and 4 data bits
